Abstract

The utility model discloses a novel turning lathe, in particular to a lathe which is suitable for turning short disc type work pieces and is especially suitable for turning threaded work pieces of oil pipelines, which comprises a lathe body connected with the lathe, a main shaft box horizontally arranged on the lathe body and a feeding system, wherein the lathe body is a tilted lathe body, a Z-directional guide rail which is tilted with the horizontal surface is arranged on the lathe body, a carriage of the feeding system is arranged on the guide rail in a sliding mode, and a vertical knife carrier is arranged on a sliding board of the feeding system and is located on the front portion of the axial cord of the main shaft. Since the tilted lathe body is adopted, the novel turning lathe has the advantages that the structural form of the front vertical knife carrier enables the whole machine to bear stronger cutting force, the cutting vibration is not easy to generate, the turning accuracy is high, and the turning lathe can be suitable for turning threads of various oil pipelines.

Description

A kind of novel lathe for machining

Technical field

The utility model relates to a kind of Metal Cutting Machine Tool, particularly relates to a kind of CNC chucking lathe that short disc type work especially is fit to processing oil pipe thread workpiece of processing.

Background technology

Than higher, especially the connecting thread of auxiliary equipment is crucial working position to the oil exploitation industry to the processing request of auxiliary equipments such as oil drill rocker, petroleum oil, sleeve pipe.These connecting threads have V-arrangement round thread, buttress thread multiple professional standards such as (being taper thread), and it not only requires to be connected firmly, and requires the reliable and higher precision of thread seal.The monodentate screw tool is used in traditional screw thread processing, the cutting that need repeatedly circulate, and efficient is low.Along with the development of cutting-tool engineering, can utilize pectination screw thread blade machining screw now, cutting edge one side of this blade has a plurality of profiles of tooth simultaneously, all participate in cutting during cutting, can reduce the cutting cycle-index like this, even can cutting at one time machine-shaping, working (machining) efficiency improved greatly.This processing also makes the cutting output of lathe increase greatly, and it is very big that cutting force becomes, and it requires bed piece, base, main shaft, planker etc. should have sufficiently high rigidity.And traditional thread cutting machine mostly is simple and easy level bed body type, low price but poor-performing, and efficient is low; Minority full function numerically controlled lathe almost all is the back knife-carrier, and rigidity is lower when cutting oil pipe thread or carrying out big cutting output, heavy cut, easily causes cutting vibration, and machining accuracy and fineness are low.

The utility model content

At the deficiency that prior art exists, the utility model provides a kind of can bear big cutting force, novel lathe that machining accuracy is high.

The utility model is achieved by the following technical solution: a kind of novel lathe for machining, comprise that the lathe bed, the level that are connected with base are installed in main spindle box, the feed system on the lathe bed, described lathe bed is oblique lathe bed, which is provided with the Z that tilts with horizontal plane to guide rail, the planker of feed system is slidedly arranged on this guide rail; Vertical knife rest is arranged on the slide plate of feed system, and it is positioned at the front portion of main-shaft axis.

Z of the present utility model is preferably 60 degree to the angle of guide rail and horizontal plane.

The utility model is owing to adopted oblique lathe bed structure, and the bed ways face not only helps chip removal horizontal by certain angle, and the lathe bed of this kind version helps improving the rigidity of lathe bed; Secondly, because nearly all oil auxiliary equipment screw thread is right-handed thread, preceding the be subjected to force direction of knife-carrier when cutting vertically pressed to the machine tool guideway face, stress is good, is difficult for causing cutting vibration, makes its machining accuracy height, then knife-carrier is stressed upwards in when cutting, form the disturbing moment of lifting backward, easily cause cutting vibration, machining accuracy is low; Adopt vertical knife rest then to avoid the interference of adjacent cutter and workpiece to the full extent.Therefore, the utility model is compared with traditional lathe, not only is suitable for the occasion of big cutting output, heavy cut, and complete machine is reliable and stable, the machining accuracy height.

Description of drawings

Fig. 1 is a lathe schematic cross-section of the present utility model;

Fig. 2 be among Fig. 1 P-P to view;

Among the figure, 1 main spindle box, 2 knife rests, 3 slide plates, 4 plankers, 5 integral protection covers, 6 bases, 7 lathe beds, 8 guide rails, 9 guide rails, 10 ball screw assembly,s, 11 ball screw assembly,s.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in drawings, a kind of novel lathe for machining comprises base 6, lathe bed 7, main spindle box 1 and feed system.Lathe bed 7 is installed on the base 6, is oblique lathe bed, which is provided with the Z that tilts with horizontal plane to guide rail 8, and guide rail 8 can be considered complete machine mechanism horizontal by 30 °, 45 °, 60 ° etc. angle, and guide rail 8 preferably is 60 ° angle with horizontal plane.Main spindle box 1 level is installed on the lathe bed 7, and it adopts concentrated reduction gear box.Feed system is located on the lathe bed, comprises planker 4, slide plate 3, and planker 4 is slidingly installed on the guide rail 8, drives it by the ball screw assembly, 11 that is located at its underpart and moves; Slide plate 3 is slidingly installed on the cross slide way 9, and guide rail 9 is fixed on the planker 4, and slide plate 3 drives it by the ball screw assembly, 10 that is located at its underpart and moves; Vertical knife rest 2 is fixed on the slide plate 3, and it is positioned at the front portion of main-shaft axis, is the forward type knife rest; Integral protection cover 5 is connected with base 6.The planker of the feed system of this machine and the ball screw assembly, of slide plate are all by servomotor and cog belt transmission.

Other parts of the present utility model adopt prior art, repeat no more here.

The utility model is rational in infrastructure, complete machine rigidity height, and the machining accuracy height can adapt to the turning processing of various oil pipe threads, can substitute import equipment on technology and performance, all has positive meaning aspect technology, the economical, societal benefits.

The foregoing description is only as to explanation of the present utility model, and is not to restriction of the present utility model.
